Abstract

L'invention concerne un équipement électronique qui est pourvu : d'une unité d'entrée (5) pour définir une région de couleur à l'instant de formation d'image, qui définit une région de couleur des informations lues d'un sujet de formation d'image qui sont lues par une unité de lecture (2) ; d'une unité d'entrée (8) pour définir une région de couleur d'unité d'affichage, qui définit une région de couleur d'une unité d'affichage (3) qui affiche les informations lues. L'unité d'affichage (3) peut modifier une région de couleur en ajustant la quantité de lumière d'une pluralité de couleurs primaires différentes émises par l'unité d'affichage (3). Dans l'unité d'entrée (5) pour définir une région de couleur à l'instant de formation d'image, une région de couleur dans une plage de région de couleur qui peut être représentée dans l'unité d'affichage (3) est sélectionnée. Dans l'unité d'entrée (8) pour définir une région de couleur d'unité d'affichage, la région de couleur sélectionnée par l'unité d'entrée (5) pour définir une région de couleur à l'instant de formation d'image est sélectionnée en tant que région de couleur de l'unité d'affichage (3). En conséquence, la définition de région de couleur pour les informations lues du sujet de formation d'image qui sont lues par l'unité de lecture (2) et la définition de région de couleur pour l'unité d'affichage (3) qui affiche les informations lues peuvent être effectuées par une définition de région de couleur unique, et les informations lues d'un grand nombre de régions de couleur sélectionnées peuvent être affichées par une unité d'affichage (3) unique sans dégradation de la qualité d'image.
